Few modern appliances deliver as many benefits as tankless water heaters. These on-demand systems provide a more reliable hot water supply, thus saving energy, space, and money. The ease of use and efficiency offered by tankless water heaters have made them increasingly popular among homeowners.
In this guide, we explain how tankless water heaters work and their advantages. We also explore the importance of professional installation.
What is a Tankless Water Heater?
Tankless water heaters differ from traditional water heaters, which store hot water in a tank and constantly heat it. Like their name suggests, tankless water heaters do not have a storage tank. Instead, cold water flows through a heating element (electric or gas) when a hot water tap is turned on. The water is heated to the desired temperature without any wastage.
As tankless water heaters do not store any hot water, they do not incur standby energy losses like traditional systems do. This makes them more efficient.
How Does a Tankless Water Heater Function?
Here is a lighter version of how the process goes:
Water Flow Initiation: When you activate a hot water tap or appliance such as a shower or dishwasher, water flow starts.
Heating Element Activation: The tankless unit heats up as it identifies the flow of water.
Water is Heatable: As water is flowing through the unit, it is heated instantaneously.
Hot Water Delivery: Once heated, water is sent immediately to the tap or appliance, retaining its processed temperature.
From a user’s perspective, water does not take time to heat up since the unit only requires the activation of a switch to begin the heating process.
Benefits of a Tankless Water Heater
Continuous Supply of Hot Water
175 continuous hours of hot-water autonomy at any faucet allows anyone to take showers, so athletes and students alike can enjoy prolonged moisture.
Efficiency in Energy Systems
When compared to other types of reservatory systems, tankless units have a higher efficiency rating; data suggests reservatory systems waste over 30% energy.
Sleek, space-saving design
Due to their wall-mounted positions, there’s no issue of bulk or room taken up on floor space.
Extended Lifespan
With proper care, tankless water heaters can outlast traditional units by nearly a decade, lasting over 20 years.
Reduced Utility Bills
Tankless systems may cost more upfront, but reduced energy consumption often results in lower monthly energy bills, creating savings over time.
Fresh Water
Without a tank where sediment builds up, tankless units usually provide fresher, cleaner water.
Optimal Situations for a Tankless Water Heater
While tankless water heaters are beneficial for many households, these situations are ideal:
Homes that have a high demand for hot water.
Small spaces where every square foot is essential.
Households want to cut back on energy expenditures.
Environmentally-conscious homeowners seeking energy-efficient renovations.
Families want value from the long-term use of appliances.
Considerations Before Installing a Tankless Unit
Before making the switch, evaluating your home’s infrastructure and specific requirements is crucial.
Fuel Type: Available in electric and gas models, tankless water heaters have gas units with higher flow rates but may need venting.
Flow Rate Needs: Hot water requirements during peak usage periods should be assessed to select the unit with appropriate GPM (gallons per minute) capacity.
Upfront Costs: While tankless systems have a higher initial purchase and installation cost compared to traditional tank systems, they recover costs over time through energy savings.
Water Hardness: The presence of hard water could influence efficiency and operational lifespan. A water softener is sometimes recommended.
Professional Installation: A tankless water heater is not a DIY project. These units need specific plumbing, electrical, and possibly gas line modifications. Professional plumbers will:
Assist in selecting the appropriate unit size and design model aligned with your needs.
Facilitate safe installation and code compliance.
Set up proper venting for gas models.
Offer warranties, maintenance instructions, and guidance.
Installation by experts guarantees optimal long-term operational efficiency and safety.
Maintenance Tips for Longevity:
A comprehensive approach is required for the regular care of tankless water heaters to sustain peak performance. To extend the life of your unit, consider the following recommendations:
Annual System Flushing: Cleaning heating elements and removing mineral buildup enhances the efficiency of heating elements.
Periodic Filter Cleaning: Regularly check the inlet filter and clean it to prevent blockage.
Scheduled Annual Professional Inspections: Comprehensive checks can detect arising concerns well ahead of actual problem manifestation.
Conclusion
Upgrading to a tankless water heater surpasses mere home improvement; it becomes an upgrade to one’s lifestyle. The savings on energy, hot water, and space become an investment in comfort, efficiency, and sustainability.
